Drying of Betel Leaves (Piper Betle L.): Quality and Drying Kinetics


Medicinal and Aromatic Plants Seminar (MAPS 2008)


21st October - 22nd October 2008

Place Held

The Legend Hotel, Kuala Lumpur


This work studied the effect of drying temperature on drying kinetics and quality of betel leaves (Piper betle L.). This medicinal plant locally known as sirih is reported to possess various beneficial bioactivities including anti-carcinogenic, anti-inflammatory, antioxidant and antimicrobial. In this study, the leaves dried at different temperatures were analyzed using High Performance Liquid Chromatography (HPLC). The quality of betel leaves was evaluated based on the change in the level of its major compounds in dried leaves was higher than fresh leaves. The major compounds increased with temparature from 40 to 60ÂșC. The increase in drying temperature shortened the drying time required. The kinetics data was fitted with different thin layer models. Logarithmic model was found to be the most suitable model to describe the drying process of betel leaves.
